True, except I believe if you have the SUP-720 which eliminates the need
for the use of the fabric modules.

The WS-X6348-RJ45V is a fabric enabled blade supporting 256gbps in the
backplane, while the WS-X6148-RJ45V is not fabric enable and runs at
32gbps in the backplane. Furthermore, there is a single ASIC on the
WS-X6148-RJ45V that allows 1GBPS throughput total for each "chunk" of
ports assigned to that ASIC. There are 6 ASICs (1-8, 9-16, 17-24,
25-32, 33-40 and 41-48), so each of these ranges are oversubscribed with
the maximum transfer speed of all 8 associated ports being 1gpbs. Also,
if you run an etherchannel on this blade, the aggregate bandwidth of the
etherchannel is limited to 1gbps. This is listed under the release
notes for the blade. The WS-X6348-RJ45V, aside from being much more
expensive, is not subject to ANY of these limitations and each port can
operate at full wire speed on every port simultaneously. However, you
also need to put another "fabric-enabling module" into the chassis to
realize the benefits of this blade which is also very expensive from
what !
I believe. If you don't include the "fabric-enabling module", the
WS-X6348-RJ45V will not utlize the fabric backplane and will operate
with the same performance of the WS-6148-RJ45V.
Please check with Cisco to verify any of this, but from MANY MANY phone
calls and conversations with them, this is the information I was able to
attain.
Hope this helps,
Ken

Hi all,
I'm building configuration for 6509 BB. I need to insert a
10/100 inline power module. I found these exact same two with different
prices. Would anyone know what the difference between them is??!!
WS-X6348-RJ45V
Catalyst 6500 48-port 10/100, Inline Power, RJ-45
WS-X6148-RJ45V
Catalyst 6500 48-port 10/100 Inline Power, RJ-45
